"evacuated tube hot water heater
I expect to install this unit when I finish building my back porch. A similar unit (owned by a friend) overheated and now leaks. I was told I needed an expansion tank and other controls to prevent this. Anyone have…"

"Hi Randy
Interesting and practical approach. A society arranged based on a community of 5,000 would offer many of the benefits of a small town with the advantages of city life. Our current provincial government has actively centralized power in the…"

Randy Chatterjee said… - Welcome, John. You have chosen a beautiful place to live.
Regarding your question on solar hydronic energy, I would first contact the Vancouver Renewable Energy Coop. Their site may have some value, but their staff have more experience than many in BC (sadly).
I am currently installing 10 PV panels on a mid-sized garden shed, and will then turn to the double (4'x16') solar-hydronic panels for the main house roof, which will feed down into a heat transfer tank to prewarm all water entering my combined DHW/Home heater. There are indeed surprisingly few people experienced in, let alone involved in, this kind of work. I also find that personally custom-built solutions and work-arounds vastly improve the performance of most off-the-shelf products.
